Dear All,
I vote *YES, *with a minor correction (verb missing):
"In the event that only a single kind of transfer of custody, either the
legal responsibility for the custody or the actual physical possession
of the object but not both, this difference should be expressed using
the property P2 has type (is type of)."
should be:
"In the event that only a single kind of transfer of custody /is to be
documented/, either the legal responsibility for the custody or the
actual physical possession of the object but not both, this difference
should be expressed using the property P2 has type (is type of).*"

Dear all,
In the last CRM SIG (47) we discussed issue 475
<http://www.cidoc-crm.org/Issue/ID-475-transfer-of-custody> which has
to do with a change to the scope note of E10 Transfer of Custody. R.
Sanderson noted that the scope note seemed to contain a contradiction
since the first line indicated that the transfer of custody was of
'physical possession' while the second paragraph indicated that it
could be of physical possession OR only of legal custody.
R. Sanderson proposed to update the scope note in order to
consistently express that the base line case is that BOTH physical and
legal custody are transferred and in the case that it is only one or
the other this would be expressed using the p2 has type property.
This proposal was generally accepted and the work of creating the
precise wording was left as homework. This HW has been provided by R
Sanderson and is in a good state for voting on.
Please find below the text of the old and the new scope note. After
having read them, please vote by replying to this email whether to
accept this change.
You may vote Yes, Yes with a caveat or No, indicating the reason for
rejecting the proposal.
Please indicate your vote by October 16th.

*OLD scope note*
*E10 Transfer of Custody*
Subclass of: E7 Activity
Scope note: This class comprises transfers of physical custody of
objects between instances of E39 Actor. The recording of the donor
and/or recipient is optional. It is possible that in an instance of
E10 Transfer of Custody there is either no donor or no recipient.
Depending on the circumstances it may describe:
1. the beginning of custody
2. the end of custody
3. the transfer of custody
4. the receipt of custody from an unknown source
5. the declared loss of an object
The distinction between the legal responsibility for custody and the
actual physical possession of the object should be expressed using the
property P2 has type (is type of). A specific case of transfer of
custody is theft. The sense of physical possession requires that the
object of custody is in the hands of the keeper at least with a part
representative for the whole. The way, in which a representative part
is defined, should ensure that it is unambiguous who keeps a part and
who the whole and should be consistent with the identity criteria of
the kept instance of E18 Physical Thing. For instance, in the case of
a set of cutlery we may require the majority of pieces having been in
the hands of the actor regardless which individual pieces are kept
over time.
The interpretation of the museum notion of "accession" differs between
institutions. The CIDOC CRM therefore models legal ownership and
physical custody separately. Institutions will then model their
specific notions of accession and deaccession as combinations of these.
Examples:
* the delivery of the paintings by Secure Deliveries Inc. to the
National Gallery the return of Picasso’s “Guernica” to Madrid’s
Prado in 1981 (Chipp, 1988)
In First Order Logic:
E10(x) ⊃ E7(x)
Properties:
P28 custody surrendered by (surrendered custody through): E39 Actor
P29 custody received by (received custody through): E39 Actor
P30 transferred custody of (custody transferred through): E18 Physical
Thing
*NEW scope note*
*E10 Transfer of Custody*
Subclass of: E7 Activity
Scope note: This class comprises transfers of the physical custody, or
the legal responsibility for the physical custody, of objects. The
recording of the donor or recipient is optional. It is possible that
in an instance of E10 Transfer of Custody there is either no donor or
no recipient. Depending on the circumstances it may describe:
1. the beginning of custody (there is no previous custodian)
2. the end of custody (there is no subsequent custodian)
3. the transfer of custody (transfer from one custodian to the next)
4. the receipt of custody from an unknown source (the previous
custodian is unknown)
5. the declared loss of an object (the current or subsequent custodian
is unknown)
In the event that only a single kind of transfer of custody, either
the legal responsibility for the custody or the actual physical
possession of the object but not both, this difference should be
expressed using the property P2 has type (is type of).** A specific
case of transfer of custody is theft. The sense of physical possession
